We divide 904086 by 2
Let's see how many times 2 fits into 904086.

Moving on to step 1:
2 goes into 9 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 8 from 9 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

Moving on to step 2:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
The remainder is 0 after subtracting 10 from 10.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 2

Moving on to step 3:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 452.0
If we subtract 4 from 4, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

Advancing to step 4:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4520.0
The remainder is 0 after subtracting 0 from 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

Let's proceed to step 5:
When dividing 8 by 2, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 45204.0
If we subtract 8 from 8, we get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

Let's proceed to step 6:
When dividing 6 by 2, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 452043.0
The remainder is 0 after subtracting 6 from 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 452043.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 452043.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 452043.0 with a remainder of 0.0.
